Aerogels posses low density , which property makes them commercially viable for various industries.The technique of forming this gel based upon the drying and removing the solvent to attain as low density as possible . Due to this property we can use these gels in activities ranging from earth to space . In Aerogels their is replacement of water with air , making it synthetic porous ultralight material derived from gel.
In past they are used as thickening agent in products ranging from colors to cosmetics .But due to certain reasons and threat of being poisonous their use is limited . But , nowadays scientist keep on searching and came up with less dangerous or complicated Aerogels . After these modification the gels again come into picture and being used by silicon manufacturers and home building structures and even in rockets building also . The major challenge is to reduce the cost of these gels to make them available at household level . Recently china develop the lowest density carbon gel replacing the graphite gel made by Germany.
